I am working on a project. I believe I need a battery that charges somewhat slow, and when full, can discharge quickly. I would be charging it with an electromagnetic induction. Therefore not a non stop current, but would be able to stop the flow of the current from coming back out of the battery once the electromagnetic induction stops. So it would be a gradual, slow process of charging the battery, but as time goes on it will eventually charge full. Once full, I would like it to be able to discharge into another battery storage of some sort, like another battery or fuel cell. I would say something sort of like a battery for a car, but I don't believe there will be enough voltage to charge it. Therefore, in summary, A battery with a lot of storage, that can be charged with low voltage, when full doesnt allow the current to flow backwards, and can be hooked up to discharge quickly into a bigger enery storage. Would definately be looking for feedback.Please and thank you. I am stumped and this is the roadblock in my journey that I can't seem to surpass. It will need to have a lot of storage closer to the car battery, and not just regular AAA batteries, as they are not enough. Definately would prefer a more eco friendly battery than just something that has a few time usages and then has to be thrown in the ground harming the environment.
